Mako-chan Kaihatsu Nikki — Episode 1

The heroine this time is Makoto, a pretty average, if not well-endowed girl. The story starts with her getting confessed to during a sunset. She accepts the confession, but things don’t progress past a kiss that evening. Her newly appointed boyfriend walks her home, where we’re shown her adoptive brother looking at them from his window with an evil grin. (Source: Fakku!)
